ADJUSTABLE' SOCKET-CLAMP FOR SUCKER-RODS.

SPECIFICATION forming part of Letters-Patent No. 521,502, dated June 19,1894.

` Application filed February 12, 1894:. Serial No. 499,932. (No model.)

To @ZZ whom it may oon/cern,.-

Be it known that we, JOSEPH A. KIDD and GEORGE W. HESS, of Haskins,county of Wood, and State of Ohio, have invented certaln new and usefulImprovements in Adjustable Socket-Clamps for Sucker-Rods; and we dohereby declare that the following is a full, clear, and exactdescription of the invention, which willenable others skilled in the artto which 1t appertains to make and use the same, reference being had tothe accompanying drawings, and to the figures of reference markedthereon, which form part of this speciication.

Our invention relates to an adjustable socket clamp for sucker rods, andhas for its object, to provide a clamp which will be convenlent inattaching and detaching the sucker rod, and which will allow of `lateralmovement at the point ot adjustment with the clamp wlthout breakage ofthe same.

The invention consists in a clamp having a lower threaded endforattachment to the valve or pump mechanism, and a cylindrical upperend slitted longitudinally to receive the lower end of the rod, a screwthreaded exterror upon which is run a threaded ferrule to compress thesections upon the rod, and socket sections having a spring extension to'compensate for lateral strain upon the rod.

The invention further consists in the parts as shown, described andclaimed.`

In the drawings: Figure 1 is an elevation of the clamp, showing the rodsecured there- 1n. Fig. 2 is a longitudinal vertical section of thesame.

l designates the socket, comprising the lower solid portion 2, having ascrew threaded end 3 and the tubular upper end tslitted longltudinallyat 5, to provide a plurality of sections 6, to allow of expansion of thesectlons to receive the end 7 of the rod. c

rlhe exterior ofthe socket is screw threaded for a dlstance along itslength, as at 8, and an internally threaded ferrule 9 is run thereon,which as the sections areexpanded the insertion of the rod, draws thesections tightly against the rod, to hold it frictionally in the socket.In order to further secure the rod within the socket, there are ribs lO,formed upon the interior of the sections preferably in staggered order,which, as the sections are drawn closely around the rodfenter the woodby corrugating the same. The upper portions of the sections are of alength to extend above the ferrule and embrace the rod, and serve asspring arms to allow lateral swaying of the rod to a certain extent.

The internally screw threaded ferrule is preferably formed with aplurality of vertical parallel grooves ll, which allow the use of aSpanner wrench in running the ferrule upon the thread.

In operation, to secure the rod in the clamp socket, the rod is insertedtherein and the ferrule run upon the sections of the clamp until the rodis tightly clamped thereon.

The clamp has an adj ustability to rods varying in size, and in its use'the employment of rivets passing through straps and the rod is avoidedwith the consequent liability of the rivets loosening and working intothe pump barrel.

The convenience with which one rod may be substituted for another andthe valuable feature of the spring ends of the clamp sections will beapparent to th'ose ordinarily familiar with this class ot devices.

While the attachment described is especially adaptable for use uponsucker rods, it can be used in all character of pumping devices, where areciprocating rod is employed.
